I enjoyed the images. The Tokio portfolio in particular seemed to have some melancholic air about it, people depicted very casually, absorbed in their activities, sometimes glancing backwards in their moving. I seem to see the fractals of a city skape, and what is more, through another one's eyes, a personal vision.
Regarding black and white: well, this is a possible vision. One must decide what to show and what not to show.
Picture 59 of the Tokio portfolio is blurred/unsharp. Was it intentionally included? If yes, I would question this decision.
